y Application filed April 15, 1889. Serial No. 307,368. (No modell) To all whom, it may concern:

Beit known that l, CARL P. STIRN, of the city, county, and Stat-e of New York, have invented certain new 'and useful-Improvements in Revolving Photographic Cameras; and I dohereby declare that the following is It consists in improved devices for moving the camera and in a novel construction and arrangements of its parts, as hereinafter described and claimed, and has for its object to simplify the apparatus and render it more compact and efficient.. f

In the accompanying drawings, Figure l is a vertical. central section of in y improved photographic camera; Fig. 2, a horizontal sec# tion in line .meot Fig. l; Figz, asimilar section in line y y; Fig. 4, a 'similar section inis produced.

linee' 2', but looking upward, so as to obtain a bottom View of the instrument and its lower gear; Fig. 5, a detached sectional View ofthe upper and lower .ends of the supply-spool and winding-reel.

Similar ,letters indicate like parts in all of` My improved camera' is constructed of a suitable oase A A, embracing an exposingchamber B of a depth somewhat greaterthan the focal distance ofthe lens to be used andi of ali-eight exceeding somewhat the diameter of its `field, and having a space C above said chamberto contain the spring-actuated meehanism by which the revolution of the camera Within the case A A is fitted a frame carrying the iilm supporting and guiding rollers and the motive mechanism. This frame consists of an upper and lower plate av (1,2 and an intermediate parallel plate a', which separates the exposing-chamber from' the compartment to contain the motor, the three plates being supported and confined in the customary manner by rods c c c c at the four corners thereof.

row compartment formed by two Vertical partitions l) b, fitted one on each side of the lens, and which extend from the front plate of the compartment being closed by a vertical rear plate b', in whiehis pierced a narrow longitudinal slit d. in alignment with the center of the lens. -Y Within the spaces left on each side 'of this leus-compartment are fitted the supply spool or roller E, on whicliis wound a sensitized iiexible photographic iilm W in readiness for exposure, and the reel or roller F, upon which the lm is wound up after exthe lens-compartment are mounted guiderollers GQ and G', over which the filmv is led guide-rollers being so located as to carry the lilm in a vertical plane in close proximity to -the outer face of the slitted plate b', closing the rear end of the lens-compartment.. rllie guide-rollers are iixed to rotate each upon .end spindles having bearings inthe top. and

ber. The spool E and 'reel F are severally mounted era The supply-spool E is provided with a central socket at each end, and a stud-pin c is fixed to project from the inner side of the top plate a to engage the socket in the upper end of the spool, while its lower end is normally engaged by a pin f, projecting upward through the bottom plate a2 from a flat springplate j", whose free end extends out beyond the edge of the bottoni plate to permit of be.- ing depressed, so as to release the pin from the spool. pin to be pressed inward to engage the end scribed, it is evident that the pin may be aetuated byothei well-known devices which will permit of its ready withdrawal to release the spool. The film-winding reel or roller F is in like manner confined iu its place and left free to rotate by means of a spring-actuated pivotpin f engaging its lower end, but which adbottom lates c and a2 of the ex osinOf-cham in manner to permit of their ready detach ment and removalfor replacement in `the camf of the spool by means of a fiat spring-plate g, serving 'as a lever for its withdrawal, as de-I The lensv D is centrally mounted in the front of thecamera,-at the outer end of anarcamera nearlyto the rear endof the exposingl chamber and from top to bottom thereof, said posure, and Y on each side o f the rear end of from the .film-spool E to the 'reel F, these Although I prefer to cause the lower IOO i mits of being,I readily withdrawnlto set free the roller, and its upper end is provided with one or more holesI at one side of 'its axis to. 'engage a counterpart pin z' or spinse' 1l, projecting from a head H, secured tova rotating spindle H', projecting into the exposing-chainber. This reelspindle l-l is mounted in suit -/a-lolebearings in the upper plate a and partition-plate a', and is fitted at itsout'er end with apinion j, meshing with a-Ytoothed Wheel I, turning,` looselyfnpon Aa winding-spindle I, but geared thereto by means of a spring-act- -ratchetfwheel K, fixed on the spindle. .This ratchet-wheel K is attached to one end of a coiled .spr-ing,` L, whose opposite end -is fixed to the frame, so that by turning" the spindle I -l by means of a key the spring; will be wound up, andwhen left free will operate to cause a revolution of the ratchet-Wheel K, and 'with it the toothedwheel I, and thereby drive the reel-spindle H. The moyementof the wheel I isprevented when desired, after the 'spring Y lis Wound up, by means of a stop consisting of a dog L', pivoted to swing' into engagement `with the teeth of said wheel to lock i-t, and .whiel'ris operated from aboveby means of a knob L on the'outer endof its axial shaft.

' A`series of sharp-pointed pins m m are titi 'ted to project radially from `the periphery of one offj the' guide-rollers G, near each end i' thereof, t'o engage the two edges. of -the sensi- I' tized film or roll 'W passed over ittrom the spool tothe rreel, and the iowe'r axial spindle yion Nto engage atoothed wheel O, screwed uponor otherwise fixed to a central head P,"-

its center in exact-alignment withwthe optical.

center or transverse axis of' theiens, and the center of this plate R is fitted upon a pivotpin r', proj ecting centrally from the head P, so as to revolve freely thereon in contact with `the upper face of the rim of the fixed wheel wheelOby mea-ns'of a screw r, screwinginto:

Q,which thus serves as 'an annular bearing therefor. The plate 'R is confined upon ythe the upper end of ther pi\fot'pin fr', and by an underlying washer ofv a diameter large Ienough to, overlap the central portionor hub ofthe plate. asshown in Fig. Il.

vTwo elastic Aradial"`ai1ns S, S are pivoted upon the headv P ,to revolve freely thereon.

" The outer 'end of each is fitted with a pin il,

to bear upwardlywith a pressure due tothe kelasticity of the arm against the rimof the 'fixed wheelO.` .c Four holes o c tz 'r are pierced through said rim, atjequal' distances apart i n: position to receive the pin fnV when itisswung into register therewith, and the "pinwv is otr such length as thatiwhen it drops into either said holes it will bearia'gain'st thexofverly ot'jsaidroller is extended' through the bottom Y v' platecof the frame `'and is tted with apin- 'ingrim of vthe annular plate R, as shown in Fig. l, and will drop into engagement 'with a singie'hoie fr', pierced in said rim, when `brought'-opposite thereto, and thereby serve A to lock said plate R, and consequently prevent arevolution of the camera, By having two of these arms S and S', if, when the camerais locked by 4one of them, the pin on the second arm is allowed to drop through either of the remaining'A holes in the wheel, and thereby bear against the rim of the annular plate R, said second pin will operate to arrest the revolution of the camera so soon as said pin reaches the stop-hole 1" inthe annular plate, and this will occur at the first, sceond, or third quarter of its revolution, according as the pin was placedA in the'iirst, second, or third Vholexfrom that engaged by the first arm.l The arms are' 'made to project far enough beyond the rim of the wheel to permit them to be readilydepressed when required foi; disengagement or adjustment.

.A perforating-bar 'l is `fitted vertically imme'diately within'ihe rear plate ofthe camera.

and in line with the slit dl in the lens-coinpartnient upon a spring-actuated push-pin T", 'projecting through said rear-plate. The inner face'of said bar T is provided with a series of sharp pins t t, of such length as that when the bar is pushed inwardly'against the Stress of the springI encircling the push-pin thel points will pierce the iilm C stretched over the slot. By means thereof, so soon an expos IOO nre has been made, the division of the picture from that next tofollow it may bc marked upon the film by pnnctures therein.

An auxiliaryguide-roller U is mounted detachably in .proximity tothe d living-roller G, between it andthe film-spool, to insure the perforation of the ilin by the driving-pins m m on saidA roller G.

-n the use and operation ol' this improved panoramic camera aspool lil, carrying` a sensi- 1 to tized photographic film (l wound up thereon, is inserted in lthe camera, andthe end of the film is carried v"around the first guide-roller G, so `as to be engaged by theA pins 'm an projecting therefrom, thence over in front of and yin close proximity to the slit in the rear plate .of the lens-chamber, and thon around the second'guide-roller G to the reel or wind ing-roller?, to which it is made/tast in the customary manner.v The spring L. is -then wound up .and is locked by the engagement l of thedog L with the toothed wheel I. The pins n n' on the arms S S may then be both made to rest on the rim of the fixed wheel O, so as to permit of a revolution ot` the camera upon its stand until it brought to the desiredinitial point .ol view, whereupon one ot the pins is allowed to drop throughone ot the apertures o in said wheel into engagement with the underlying aperture @"inthe annular bearing-plate R, carrying' thevcamera, so as to lock it. 'If new' thespring il be set free, it will exert its'tension; by means of thein-v te-rvtmingy near; asdeeeribfrl. upon the wind will @ausegthe cani era to revolve .upon its axis, Q'O

So M soon, however, as the locking-pin n' is disengaged the tension ofthe spring will operate to Wind upthe'film on the roller vproducing thereby a rotation ofthe` roller G said axis being coincidentwith the focal-axisof the lens.l As the locking-pin n, when disengaged from thehole o in the bearing-plate R,
